[9] Heating and cooling set point ranges
The purpose of this field setting is to prevent the user from selecting
a wrong (i.e., too hot or too cold) leaving water temperature. Thereto
the heating temperature set point range and the cooling temperature
set point range available to the user can be configured.
■
[9-00] Heating set point upper limit: maximum leaving water
temperature for heating operation.
■
[9-01] Heating set point lower limit: minimum leaving water
temperature for heating operation.
■
[9-02] Cooling set point upper limit: maximum leaving water
temperature for cooling operation.
■
[9-03] Cooling set point lower limit: minimum leaving water
temperature for cooling operation.
[9-05~9-08] Automatic setback function
Setback function provides the possibility to lower the water
temperature during space heating. The setback function can for
instance be activated during the night because the temperature
demands during night and day are not the same.
■
[9-05] Status: defines whether the setback function is turned
ON (1) or OFF (0)
■
[9-06] Start time: time at which setback is started
■
[9-07] Stop time: time at which setback is stopped
■
[9-08] Leaving water setback value
A Normal leaving water temperature set point or calculated
weather depended set point
B Calculated leaving water setback temperature set point

INFORMATION
■
Make sure the domestic water is only heated up to the
domestic hot water temperature you require.
Start with a low domestic hot water storage
temperature set point, and only increase if you feel
that the domestic hot water supply temperature is not
sufficient for your needs (this depends on your water
using pattern).
■
Make sure the domestic water is not heated
unnecessary. Start with activating automatic storage
during night (default setting). If it seems that the
domestic hot water night storage operation is not
sufficient for your needs, an additional scheduled
reheat during daytime can be set.
NOTICE
The setting [4-03] shall not be modified. The installer
selected the proper setting for your application.
INFORMATION
The status of this setting is only mentioned to indicate
which settings and functions are applicable for your
application.
[4-03]=4 is only for domestic hot water tank with built-in
electrical booster heater (EKHW*).
[4-03]=5 is only for domestic hot water tank without
electrical booster heater (EKHTS).
CAUTION
■
In case of a floor heating application, it is important to
limit the maximum leaving water temperature at
heating operation according to the specifications of
the floor heating installation.
■
In case of a floor cooling application, it is important to
limit the minimum leaving water temperature at
cooling operation (field setting of parameter [9-03]) to
16~18°C to prevent condensation on the floor.
INFORMATION
■
Remark that the b icon will be flashing during setback
operation. The calculated leaving water setback set
point is
not shown during setback operation.
■
By default the setback function is disabled.
■
The setback function can be combined with the
automatic weather dependent set point operation.
■
Setback function is an automatic daily scheduled
function.
■
The setback function can be combined with the
schedule timer. When setback is active, the scheduled
space heating set point will be lowered with the [9-08]
leaving water setback value.
INFORMATION
Only applicable if [4-03]=4 or 5!
It is advised to set the start time of automatic storage
during night [6-04] on the moment that the setback function
starts [9-06].
INFORMATION
Pay attention not to set the setback value too low,
especially during colder periods (e.g. winter time). It is
possible that the room temperature can not be reached (or
it will take a much longer time) because of the big
temperature difference.
